V FRANCIS J. HERRON AND EMIL M. HUGEN'IOBLER, OF NEW YORK, N. Y.

FUEL-CARTRIDGE.

SPECIFICATION forming part of Letters Patent No. 379,697, dated March20, 1888.

(No model.)

To all whom, it may concern:

Be it known that we, FRANCIS J. HERRON and EMIL M. HUGENTO'BLER, of thecity, county, and State of New York, have invented certain new anduseful Improvements in Fuel- Oartridges, of which the following is acomplete description, reference being had to the accompanying drawings,forming part of this specification.

Our invention relates to that class of fuelcartridges for burningmineral oils or liquid hydrocarbons which consists of a body or core ofabsorbent material inclosed in a perforated or foraminated shell, thecombustion of the oil taking place at the perforations of theshell afterthe cartridge has been impregnated there with; and the object of ourinvention is to construct and proportion said cartridges, whereby slowerand better combustion may be secured.

In the accompanying drawings, Figure l is a vertical section of ourcartridge,the left-hand half of said section being on the verticalradial plane X and the righthand half on the vertical radial plane Y.Fig. 2 is a perspective view. Fig. 3 is a horizontal section on lineZ,with the filling of the cartridge removed. Fig. 4 is a view of one ofthe side pieces or staves which form the sides of our cartridge.

Our cartridge is cylindrical in shape. It consists of two heads, A A,(the lower one with suitable lugs or supports, 1,) held together by.means of the bolt B and loopshaped nut N,

the latter affording means for lifting and carrying the cartridge. Thesides of the cylinder are formed by a series of pieces or staves, S, ofequal length. The ends of these staves fit in annular grooves on theheads A, formed between a rim running along the edges of said heads andan annular rim or circular rib, d, also on said heads A. \Vhen the boltB is drawn up, the staves S becomelocked in position, and cannot,therefore, shift either inwardly or outwardly. The heads A are furtherstiffened by means of radial ribs 1".

The staves S are serrated on their edges, as shown at it, so that whenthe cartridge is filled with asbestus, mineral wool, or other absorbentmaterial, C, rammed therein, the oil absorbed thereby will burn at theinterstices in the cylindrical shell formed by the indentations on theserrated edges of the staves S. The object of this mode of constructionis to providea limited area of burning-surface, instead of having thefire spread over the whole surface, as is the case when wire-netting orperforated metal is used to form the cylindrical part of the cartridge.This insures slower combustion, and by dividing the flame provides forits more intimate contact with the surrounding air, and therefore forbetter combustion.

To further enhance combustion, the staves S are depressed longitudinallyin their center,as may be seen in Fig. 3. Opposite such depressious areprovided openings a in the heads A, through which openings air from theends of the cartridge (where there is no flame) may be admitted alongthe depressions in the staves S to the flame burning on the serratededges of said staves.

What we claim as our invention, and desire to secure by Letters Patent,is-

1. In a fuel-cartridge of the kind described above, in combination, thetwo heads provided with grooves on their inner faces, the staves havingtheir edges serrated and their ends engaging into said grooves on theheads, and a central through-bolt to draw the heads together and securethe staves in position, as shown and described.

2. In a fuel-cartridge of the kind described above, in combination, thetwo heads provided with grooves on their inner faces and suitableperforations, the staves having their edges serrated, their endsengaging into said grooves on the heads and their centers depressedlongitudinally and inwardly, the ends of said depressions matching theperforations on the heads, and, lastly, a central through-bolt to drawthe heads together and secure the staves in position, as shown anddescribed.

In witness whereof We have hereuntoset our hands this 24th day ofSeptember, 1887.
